- 15SoluteWhat is being soluted, the minor component of the solution
- 16SolventWhat is dissolving the solute, the major part of the solution
- 17Colligative PropertiesRatio of solutes and solvents
- 18Non-VolatileNon-reactive
- 19Homogeneous MixtureMixture in which the components are evenly distributed
- 20SolutionMixture in which a solvent dissolves and distributes the solute
- 21Heterogeneous MixtureMixture in which components are not evenly distributed
- 22SuspensionMixture of undissolved particles in a heterogenous solution
- 23MiscibleSomething that forms a homogenous mixture is formed
- 24Unsaturated SolutionSolution where there is not enough solute added
- 25Saturated SolutionSolution at which the saturation point and an equilibrium are reached
- 26Supersaturated SolutionSolution with too much solute
- 27SolubilityThe point at which the solution is saturated
- 28DiluteA solution in which there is more solute than solute
- 29MolarityNumber of moles of a solute per a liter of that solution
- 30PrecipitateSomething deposited out of a solution as a result of the solution being saturated already
- 31SolubleCapable of being solved, distributed evenly in a saturated solution
- 32InsolubleIncapable of being solved or reaching a saturation point
- 33LeChatelier's PrinciplePrinciple that dictates that when a reaction in an equilibrium is put stress upon, it makes changes to restore the needed equilibrium

- 41Alternative Theory AcidAccording to Alternative Theory, acids give up a proton to the base
- 42Alternative Theory BaseAccording to Alternative Theory, bases receive the donated protons from acids
- 43pHState of acidity or basicity of a substance
- 44pH ScaleScale that rates the substance neutral, basic or acidic
- 45TitrationTechnique of determining the unknown molarity of a base or an acid with its opposite’s known molarity, using the equation MaVa=MbVb
- 46EndpointStage of the titration at which the indicator signals a balance between acids and bases
- 47Equivalence PointPoint at which the substance during a Titration is neutralized
